As Sleepy Hollow wraps up its third season, the Fox drama is gearing up for one of the biggest episodes yet.

In the aftermath of The Hidden One's (Peter Mensah) ascension to his current all-powerful state, Jenny (Lyndie Greenwood) is reeling from the loss of Joe (Zach Appelman), while Ichabod (Tom Mison) and Abbie (Nicole Beharie) are in the catacombs with Crane's former partner, Betsy Ross (Nikki Reed).

It all leads to the ultimate showdown in the Season 3 finale, "Ragnarok," as Team Witness takes on its toughest opponent to date. For a show that has excelled in jaw-dropping twists, this hour ranks as one of the most powerful, game-changing installments of the series.

When the Sleepy Hollow cast and co-executive producer/writer of the finale, Raven Metzner, were at WonderCon in late March, they shared a few of their own (spot-on) teases about the hour.
